SPEIFICATION 'forming part of Letters Patent No. 318,52'22'x dated May 26, 1885.

Application filed January 16, 1855. (No model.)

To cL-ZZ whom it may concern:

Be it known that I, EnNEsTn Ito'rHLrsnna- GER, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Apparatus for Lining Bands of WheelIIubs, of which the following is a specification.

)Iy invention relates to an apparatus for spinning the lining of a hub-band upon the interior of the band after it has been driven upon the hub of the wheel.

Previous to my invention various methods of securing the ornamental lining of huobands were employed, all of which necessitated the placing ofthe lining in position within the band and securing it before the band was driven upon the wheel. As the linings were turned out over the end of the band, and usunally made of thin polished sheet metal, the lining was injured in the driving of theloand upon the wooden hub of the wheel. Not only was the polished surface of the sheet metal injured, but the driving of the band stretched and loosened the lining, injuring its ornamental appearance as well as durability. My invention effectnally obviates all these diiliA culties, and allows the lining of the band to be spun within the hand after it has been driven upon the wheel, which is accomplished by means of a peculiar tool operated in the manner hereinafter explained in the description of the accompanying drawings, making a part of this specification, in which- Figure l represents my improvement in position for spinning the lining. Fig. 2 isa plan View of the inner end of the tool-stock. Fig. 3 is a central longitudinal section of the spinning-tool.

A represents the outer end of the hub for an ordinary carriages/heel.

B represents the metal band, driven thereon.- It is shown as provided with a shoulder, c, over which the lining C is spun. The outer end, G', of the lining is shown as turned over the end of the hub.

In order to spin the metal over the shoulder a, I provide the following tool:

I) represents an aunulus, attached to the interior projecting cylinder, d, which loosely fits within the hub of the band I3 and lining C,

and which rests against the lining of the hubband.

c represents an annular recess, chased in the inner periphery of the annulus D. This recess serves as a bearing for the spinning-tool. The spinning-tool is composed ot" a revolving stock, E, provided with a disk, e, which fits and journals in the recess c of the holdingring D.

L representsI the interior of the stock E, which is shown of rectangular form.

F F represent arms, pivoted at their upper ends within the outer end of stoel; E and on opposite sides thereof. They are provided with projecting inclined surfaces g. Upon the outer ends are journaled compressing-rollers G G, which are journaled upon centers b projecting from the outer ends of arms F. The centers are preferably made of screws. The pcripheries of rollers G are formed with a concave surface, h, with a forwardly-projecting lip, which serves to turn the lining over onto the shoulder a. The peripheries of the rollers G are made to conform to the shape of shoulder a, so that the lining C may be pressed firmly down over the shoulder, the shape of which may be variously modified.

H I-I represent springs, which seat in the arms F and bear against the interior of the periphery of stock E, which serves to compress and keep the arrnsF and the rollers G normally in the position shown 'in Fig. 3, so that the tool may be readily inserted and pass the narrowest point of shoulder a, and readily withdrawn therefrom.

In order to spread the arms F and rollersG apart, so that the periphery of the rollers will bite and bear against the lining C, I provide a tapered plunger, I, which fits against the inelines g of the arms F. As the plunger I is pressed inward, it spreads the rolls G and causes them to bear against the lining C.

K represents a shank, adapted to engage in the socket of abrace-stock, so that the tool may be revolved. The plunger I, arms F, rollers G, and stock E being revolved as plunger I is pressed inward, it spins the flange of lining C over the shoulder a.

In order that the plunger I may he reciprocated longitudinally, and yet be held in place, I provide a slot, @which engages with a pin, k,

IOO

which projects inward from the sides of the guide L. Vhen pressure is removed from the shank K, the springs II, bearing against the arms F, press the plunger Ibackward, and the parts automatically come into the position shown in Fig. 3, so that the tool may be readily withdrawn from the hub.

In securing lining C to the hubband B the outer iiange, C, may be spun over first by a suitable tool, and then the spinning-tool herein shown and described forspinningthe inner flange, O, isapplied.

By the use ofthe tool herein described the lining may be readily and rapidly secured to the band B after it has been driven upon the hub A, making at once aneater and more durable finish for the band of the wheel.

s t represent wings orguides,pro]`ecting from the sides of the stock outward, so as to serve as guides bearing in the cylinder d, the stock being cored or cut away, the points marked c are simply for lightening the stock, which might be made cylindrical throughout its entire length on its exterior, and of any shape upon the interior to correspond with the arms FF and plunger I, reciprocating longitudinally within the space L, for the purposes above specified.

Instead of turning the tool E by means of the shank K, the latter may be held in position and the wheel-hub A and band B revolved upon the tool and accomplish just the same resultsas here specified, the plunger I being pressed inward, so as to turn the shoulderover in the desired manner.

What I claim as my invention is- 1. Aspinning-tool consisting of a revolving .stock carrying one or more revolving pivoted rollers, G, adapted to spin and turn the inner end of the hub-lining over the flange inside of v.ro

' ing of hub-bands after they are placed on the wheel,consistingot` stock E,and arms F F, carrying shaping or spinning surface It upon their inner ends, adapted to be spread to turn the lining over the shoulder a as the parts are revolved, substantially as specified.

5. In combination with the stock E, the spreading-plunger I, arms F F, spinnin'gsurface h, and springs H, whereby the too'l is readily inserted into the hub, and the lining spun over the shoulder as the tool is pressed inward, substantially as herein specified.

6. In combination with the stock E,the plun- A ger I, provided with grooves t', and guide k, adapted to spread two spinning-tools, G, as the plunger I is pressed inward, substantially as specified.

In testimony whereof Ihave hereunto set my hand.
